Everything about Positive feedback

Loop that increases an initial effect

Positive feedback is a process that occurs in a feedback loop where the outcome of a process reinforces the inciting process to build momentum. As such, these forces can exacerbate the effects of a small disturbance. That is, the effects of a perturbation on a system include an increase in the magnitude of the perturbation. That is, A produces more of B which in turn produces more of A. In contrast, a system in which the results of a change act to reduce or counteract it has negative feedback. Both concepts play an important role in science and engineering, including biology, chemistry, and cybernetics. Wikipedia →

đź“– Definitions

Noun A situation where some function of the output of a system, process, or mechanism is fed back in a manner that tends to increase any divergence of the output from its initial value.

Noun A feedback loop in which the output of a system is amplified with a net positive gain and added to the input signal before the main amplifier.

Noun Feedback which builds upon previous feedback.
